Why Copper is Critical to the Best DRAM Technology

Yesterday we announced our 42nm DRAM technology with a 2Gb DDR3 device. If you just skimmed the headlines, you could have missed an important point—our DRAM is built with copper for critical metallization layers (not aluminum, like some others are). Now, that might be something you’re tempted to shrug off, “Isn’t DRAM just built to standardized specs? Does the metallization type really matter?” It absolutely does as we move below 50nm process technology and DRAM product specifications become more demanding and complex.
